The present application is directed to a method of treating osteoarthritis which includes obtaining a member of a transforming growth factor superfamily of proteins; obtaining a population of cultured connective tissue cells that may contain vector encoding a gene, or a population of cultured connective tissue cells that do not contain any vector encoding a gene; and then transferring the protein and the connective tissue cells into an arthritic joint space of a mammalian host, such that the activity of the combination within the joint space results in regenerating connective tissue.

Why it's free to use
- Filed March 12, 2003 and granted May 13, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 12, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
